Cross-Domain Empirical Risk Minimization for Unbiased Long-Tailed Classification

2022 · Proceedings of the AAAI Conference on Artificial Intelligence

We address the overlooked unbiasedness in existing long-tailed classification methods: we find that their overall improvement is mostly attributed to the biased preference of "tail" over "head", as the test distribution is assumed to be …

DiGeo: Discriminative Geometry-Aware Learning for Generalized Few-Shot Object Detection

2023 · arXiv (Cornell University)

Generalized few-shot object detection aims to achieve precise detection on both base classes with abundant annotations and novel classes with limited training data. Existing approaches enhance few-shot generalization with the sacrifice of base-class performance, or …

Investigating Video Reasoning Capability of Large Language Models with Tropes in Movies

2024 · arXiv (Cornell University)

Large Language Models (LLMs) have demonstrated effectiveness not only in language tasks but also in video reasoning. This paper introduces a novel dataset, Tropes in Movies (TiM), designed as a testbed for exploring two critical …
